THE TRANSMISSION SHOP
SNELLVILLE CALLS IN JULY

Every July, when the heat sits on Highway 78 and the crawl into Atlanta turns in to a parking lot, the phone starts. "My car jerks when it shifts. Is the transmission going?" Usually not. Hot, tired fluid and a gearbox that has forgoten how to shift is the common story. Nine times in ten the transmission stays in the car were it belongs.

Snellville is hard on a gearbox. The stop and go on 78, the Ronald Reagan on-ramp where you floor it into a gap, the summer heat cooking the fluid untill it turns brown. Fluid the maker once called lifetime dosent last a lifetime here. Once its worn, the clutches slip a little on every shift and wear out early.

A harsh shift or a gearbox warning mean come in soon. Slipping, a flare between gears, or a shudder at lite throttle means come in this week. Stuck in gear means dont drive it, call us. We're the German auto repair shop in Snellville that reads the car before any transmission repair starts, and we've been fixing the fault insted of selling the rebuild since 2010.

What's included

TRANSMISSION REPAIR OR
TRANSMISSION REPLACEMENT

Technician lowering a transmission from a lifted Mercedes G-Class at German Performance

German automatics are built to last the life of the car, and their built to be serviced, not ignored. Thats why the word lifetime on the fluid causes so much trouble. Serviced on time and diagnosed propperly, most never come out of the car.

  • Every fault read on the factory software before anyone says rebuild
  • Fluid and filter to the exact spec, filled at the tempature the book says
  • Every transmission repair leaves with a 12-month, 12,000-mile warranty
01

Fluid and Filter Service

ZF 6HP and 8HP, Mercedes 7G and 9G, and Porsche PDK all have a fluid the maker once caled lifetime and a filter built into the pan. Heat wares it out. We replace both with the fluid your car specifys, filled and level checked at the right temperature.
02

Mechatronic and Valve Body

Harsh shifts, a flare between gears and a gearbox warning very offen trace to the valve body and its solenoids, or the mechatronic unit, the computer that decides when to shift. Read on the factory software, that's a repair, not a rebuild, and a hole lot cheaper.
03

Adaptations and Software

Modern gearboxes learn how they shift. After new fluid or a repair those values are wrong, so we reset them threw the factory software and relearn them on the road test. Skip that step and a good service feels worse befor it feels better. We also load any shift update the maker has relesed.
04

DSG and PDK Service

Volkswagen and Audi DSG, BMW DCT and Porsche PDK use wet clutches that share thier fluid with the gearbox. Each one has a publised interval, 40,000 miles on the common DSG units. Skipping it is the most comon way we see a clutch pack die early.
05

Torque Converter Shudder

A shudder at light throttle, like rolling over rumble strips, is usually the lock-up clutch in the torque converter. Worn fluid is the common cause and it often clears up after a fluid service. We test it on the road with live data and tell you wich one it is.
06

Leaks, Seals and Mounts

Pan gaskets, the plastic sleeve where the wiring enters the case, cooler lines and output seals are the usuall leak points. A worn transmission mount make a good gearbox feel rough and clunky in reverse. All of it is routine too put right, and none of it means the gearbox is bad.

Great price

I bought my BMW secondhand and it came with a whole list of issues, so I brought it to Zayd and his team and I'm so glad I did. They fixed my bumper, took care of some engine repairs, and even helped me install customizations including a new steering wheel, front lip, bumper, and side skirts. The whole team was great to work with from start to finish. Honest, skilled, and they clearly take pride in their work. Anytime I need anything for my car, this is where I'm going. Highly recommend!

I had an excellent experience at this shop. I brought my car in, and from start to finish the service was outstanding. The team was professional, honest, and took the time to explain everything they were doing. They did an absolute 10/10 job, and the quality of the work exceeded my expectations. Their pricing was also very fair, especially considering the level of service and attention to detail. It’s hard to find a shop you can truly trust, but these guys definitely earned my business. I highly recommend them to anyone looking for reliable, high quality work on their German vehicle. I’ll definitely be coming back!

FAQ

Who's the best transmission shop near me in Snellville?

Ask around Snellville and our name comes up alot. German cars only since 2010, 180+ Google reviews and a 4.8 CARFAX rating. Come by, meet the person who'll do your transmission repair, and decide for yourself.

My fluid is supposed to be lifetime. Does it really need changing?

Yes. ZF, who builds the automatics in most BMW, Audi and Porsche models, recomends changing it every 50,000 to 75,000 miles. Fluid breaks down with heat and miles, and the gearbox it protects costs far more then the service.

What does a slipping or jerking shift usually mean?

On a German automatic it most often means worn fluid, a valve body or mechatronic fault, or adaptations that has drifted. All three shows up on the factory software. A worn out gearbox is the least likley cause, not the first guess.

Can you repair the transmission instead of replacing it?

Very often. Valve bodies, solenoids, mechatronic units, seals, cooler lines and mounts all gets fixed in the car. When the clutches or hard parts inside are truely worn, we'll show you the evidence and walk you through the options.

Why does the car need to relearn after a transmission service?

Modern gearboxes adjust shift pressure as the clutchs wear. New fluid or a repair makes those learned numbers wrong, so we reset them and the car relearns on the road test. Thats why some services feel rough for a day, then settle.

Will a transmission service fix a shudder?

Sometimes. A shudder at light throttle is usually the torque converter's lock-up clutch, and old fluid is the comon cause. A fluid service is were we start. If the shudder stays, the converter is the next conversation, and we'll have diagnossed it, not guessed.
